How to deal with chili seeds before sowing?

How to deal with chili seeds before sowing? Please introduce that pepper seeds can be treated as follows before sowing: 1. Sunning: spread the seeds in a dustpan for 1-2 days before sowing (do not sun the seeds directly on the balcony), which can enhance seed vigor, improve germination rate and germination potential, and accelerate germination and emergence. It also has certain sterilization and disinfection effect. When sowing with old seeds, you must dry the seeds before sowing, and the effect is particularly remarkable. 2. Seed disinfection: pepper seeds can carry pathogens of anthracnose, blight, quenching, blight, scab and other diseases. Disinfection of seeds before sowing is one of the simple and easy methods to control diseases. Hot water blanching: in order to kill germs attached to the surface of the seed and latent inside the seed, hot water can be used to scald the seed. First soak the seeds with water, which can reduce the effect of hot seeds on seed germination, and promote the pathogens on the seeds to germinate, which is easy to burn to death. Drain the soaked seeds and blanch them in 52-55 ℃ of hot water for 15 minutes. In order to ensure the effect of sterilization and disinfection, one is to ensure the temperature of the water. Cuttings into a thermometer, when the water temperature drop on the hot water; second, to achieve the prescribed time for blanching. Immediately after scalding the seeds, take the seeds out of hot water and put them into cold water to cool them, so as not to damage the seeds. Medicament disinfection: first soak the seeds in warm water for 4-5 hours. After starting water, soak in 1% copper sulfate or 0.1% potassium permanganate aqueous solution for 5 minutes, or soak in 100 times formalin solution for 20 minutes. To prevent pepper virus disease, the pre-soaked seeds can be immersed in 10% trisodium phosphate solution for 20 minutes. Soaking the pre-soaked seeds in 1000mg/kg 's agricultural streptomycin solution for 30 minutes has a good effect on the control of scab and bacterial wilt. After soaking the seeds with chemicals, rinse the seeds with clean water before they can sprout or sow directly. Otherwise, the germination of seeds will be affected. Dry heat treatment. Dry heat treatment of fully dried seeds in a 70 ℃ incubator for 72 hours could kill many pathogens without reducing the germination rate of seeds. In particular, it is effective in preventing viral diseases. 3. Soaking seeds to accelerate sprouting: those with high air temperature and bed temperature when sowing seeds, such as those before the Beginning of Winter sowing, directly sow dry seeds. On the contrary, sowing seeds in the cold season, in order to accelerate the emergence of seedlings, generally soak the seeds first to promote budding. However, if the germinated seeds are sown in the seedling bed and encounter a cold wave, the climate is cold for a long period of time, and if there is no heating equipment in the seedling bed, the seeds may rot and lack seedlings. On the other hand, it is safer to sow dry seeds and not easy to rot. The electric hotbed first soaked the seeds to promote sprouting. Different varieties of spicy (sweet) pepper have different seed soaking time. In general, the soaking time of spicy (sweet) pepper seeds should be 8-10 hours. After the seeds are immersed in water, stir, remove the floats, and scrub off the contaminants on the seed surface. Then, drain the water and wrap it in a cloth and put it in a place of 25-30 ℃ to accelerate the germination. You can use an incubator to promote sprouting. The heat of the available electric lamp without such equipment (simple sprouting carton) the residual heat of the stove, or in a thermos bottle containing half a bottle of hot water, or in a heated compost. A small amount of seeds can also be wrapped in a wet cloth, then wrapped in a plastic film, placed in a close-fitting lining bag or hatched chicken nest, using body temperature to promote germination. In the process of accelerating germination, it should be turned frequently, and when the seed is too dry, it can be infiltrated with warm water. Pay attention to prevent seeds from being scalded by high temperature. If the temperature is too low and mold occurs on the seeds for a long time, the seeds should be washed with warm water and continue to sprout. Generally, after 5-7 days, most of the seeds can be sown. Click to get more chili planting techniques click to get more vegetable planting techniques
